Karner Blue Butterfly Project

Part of the Praxair Surface Technologies (PST) property in Concord, NH, is the last known location in the Northeast of the federally endangered Karner blue butterfly, PST employees partnered with the New Hampshire Fish and Game Department to take a proactive role in restoring the butterfly population on its land, PST employees cleared timber and brush and planted over 600 native lupine and other nectar plants, which serve as food sources for the butterflies. Praxair's Global Giving Program also provided funds to purchase lupine plants for Concord schoolchildren as part of the "Kids for Karners" program. As the program continues, PST employees hope to plant up to 15 acres of lupine in order to restore the butterflies' habitat and eventually increase the population of the species.

The Need

The population of the Karner blue butterfly declined from 3,000 in 1983 to fewer than 100 by 1994. The decline was primarily caused by the loss of wild blue lupine, a food source for the developing caterpillars.

Making our Planet More Productive…

by working to increase the population of an endangered species and the ecosystem on which it depends.

The amount of work that was completed by Praxair in such a short period would have taken a week or more for our limited staff to complete. The plantings doubled the amount of existing habitat, which will support the butterflies that are released from the captive breeding program.
